4604 THE ZOOLOGIST—SEPTEMBER, 1875, 
perfectly straight tail. This and the next species appear to be “ di- 
morphic,” a wholecoloured? and a particoloured bird being often 
found paired, and the difference in plumage seems to be irrespective 
of sex or age; but on this point further information is desired. 
* Buffon’s Skua (Stercorarius longicaudatus).—Said not to breed 
further south than lat. 70° N. One example obtained by the 
Germans. To be distinguished from the last species by its smaller 
size, more slender bill, and, even on the wing, by its exceedingly 
long tail. Would seem to be rather less “dimorphic” than 
S. parasiticus. 
*Fulmar or Mallemoke (Procellaria glacialis). “ Kakordluk,” 
“ Kakordluvek ;” dark variety, “Igarsok.”—Said not to breed further 
to the south than lat.69° N. Occurs also in East Greenland (Pansch). 
A very unmistakable bird, but worthy of attention, since individuals 
vary a good deal in the shade of colouring. The young are sup- 
posed to be darkest in hue, but some seem to keep this sign of 
immaturity all their life. 
t+Greater Shearwater (Puffinus major). “ Kakordlungnak.”— 
Marked by Prof. Reinhardt as breeding in Greenland, and said by 
Holbéll to be found in great numbers from the southern point of 
the country to lat. 65° 80’ N.; the eggs of this bird are utterly un- 
known. Shearwaters of some species have many times been noticed 
in abundance off Cape Farewell. 
Gray Shearwater (Puffinus Kuhli).— Only known from 
Greenland by a specimen received thence by Herr Méschler 
and now in the Leydon Museum (Schlegel, Mus. Pays-Bas, 
Procellariz, p. 24). 
Manks Shearwater (Puffinus anglorum).— Once received 
from Greenland. The changes of plumage undergone by 
shearwaters seem to be somewhat analogous to those of the 
skuas, and no ornithologist at present has been able to give a 
rational explanation of them. 
+ Forktailed Petrel (Thalassidroma Leachii).—Constantly ob- 
served near the coast to lat. 64° or 65° N., and most frequently about 
the entrance of Godthaab Fjord, on the islands of which it is said 
to breed.? 
1 Tt is to this wholecoloured form that the name §, Richardsoni properly applies. 
2 Two examples of the common stormy petrel (Procellaria pelagica), with the 
locality ‘‘ Groénland” are contained in the Museum of Leyden, having been received 
direct from Holbéll, who doubtless obtained them on one of his voyages, but whether 
in the Greenland seas is another matter.
